Summary of measurements
-Deployment of moorings (current meters, ADCP, thermistor chains, CTD for fluorocarbons) for 1 year. -Subsurface floats released in Levantine Intermediate Water for 1 year. -Synoptic study using SEASOAR undulating towfish and EK500 echosounder. -Deployment of a drifting line with 3 PPS4 particle traps. -Vertical net hauls from 0-200 m/zooplankton, horizontal hauls at surface/hyponeuston net. -CTD stations and rosette samples. -Biogeochemical readings from XBT shots. -Sampling and in situ pumping to study cesium isotopes in the Levantine Intermediate Water. -Vertical profiles taken from 0-1,000m with the marine video profiler. -NOAA/AVHRR satellite data received and analyzed onboard.
